GEOLOGY

Detailed explanation-1: -Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism. The protolith is subjected to heat and pressure causing profound physical and chemical change. The protolith may be sedimentary rock, igneous rock, or another (older) metamorphic rock.

Detailed explanation-2: -Answer: The process of transformation of rock of one type into another is called as metamorphism. Explanation: Metamorphism : Metamorphism is the process of conversion of one type of rocks into another type under the effect of high temperature and pressure.

Detailed explanation-3: -Igneous and metamorphic rock can be buried and undergo tremendous heating and stress.

Detailed explanation-4: -Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word “metamorphic” comes from Greek and means “To Change Form".

Detailed explanation-5: -Transformation of rocks from one form to another is called the rock cycle. For example, molten magma cools and becomes an igneous rock. It then breaks down into sediments and then forms a sedimentary rock under great pressure. The same rock can become a metamorphic rock when subjected to great heat and pressure.
